Patented Mar. 13, 1934 .LFITED STATES PATENT OFFICE 1,950,655 STOCK STRAIGHTENER Alwyn E. Borton, South Orange, N. J., assignor to Associated Manufacturers, Inc., Ampere, N. J., a corporation of New Jersey 7 Claims.

The present invention relates to the art of metal-working and particularly to the straightening of the stock as it enters the machine.

A multi-slide machine such as this invention is particularly related to, is disclosed in United States Patent 1,883,513 of October 18th, 1932, the present case being a division of that patent.

Special objects of this invention are to provide a straightener for strip stock, wire, or the like, of simple, sturdy construction, readily adjustable to various forms and sizes of stock, which can be readily opened up for threading the stock through and quickly closed to operative relation and which will be particularly accurate and reliable in its operation.

The drawing accompanyingand forming part of this specification illustrates one of the actual commercial embodiments of the invention, but it will be appreciated that the structure may be modified as regards this particular showing, without departure from the true spirit and broad scope of the invention.

Fig. 1 is a broken straightener.

Fig. 2 is a broken view of the entering end portion of the straightener.

Fig. 3 is a broken view of the opposite end portion and a part sectional illustration as on line 3-3 of Fig. 1.

The base of the straightener designated 5, is shown in the nature of a supporting bracket attachable to the end of the machine frame. This supporting bracket carries at the free end of the plan view of the strip same an open top box or casing made up of a stationary portion 6, forming an integral part of the base structure and a movable portion '7 hingedly mounted on the base structure at 8, below and substantially in the vertical plane of the feed line. That part of the bracket which carries the hinge pin 8, is shown as having an outwardly projecting lug 9, in the general horizontal plane of the hinge pin and as having a vertical screw passage 10 therethrough for the hand screw 11, which has a bearing against the pad 12 on the underside of the movable box section 7.

The straightening rolls are arranged in two sets and in alternating order, at opposite sides of the feed line. The rolls of one set are designated 13 and the rolls of the other set as 14.

Each roll is journalled on a vertical pivot 15, in a parallel sided block 16 and these blocks fit side-by-side in slidable relation, between spacing shoulders 1'7 and 18 in respective box sections 6 and 7.

The roll carrying blocks 16 have a sliding mounting at 19 on the bottom of the box sections as indicated in Fig. 3 and they are secured rigidly down on their seats by the vertical screw bolts 20 extending down through slotted portions 21 in the blocks.

Individual setting of the blocks and hence of the rolls carried thereby is effected by adjusting screws 22, extending through the sides of the box sections and engaging the box, said screws being secured in adjusted relation by lock nuts 23.

To assure parallel relation of the rolls of the two sets, cooperating meeting stops are provided at 24, 25, at the opposite ends of the relatively.

stationary and movable box sections. These prevent the hinged sections from being rocked to such a position as to cramp the stock and the solid engagement of these stops assures the operator that the rolls are in true parallelism.

To position and accurately guide the stock vertically, edge guiding rolls are shown at 26 and 27, one positioned to engage the lower edge of the stock and the other placed to engage the upper edge of the stock.

These rolls may be grooved or smooth, dependent upon the character of stock and other conditions. In the illustration, the lower roll is simply a straight roll extending across the feed line and the upper roll is shown as grooved in line with the feed line to fit over the upper edge of the stock.

The edge guiding rolls are shown as carried respectively by the stationary and movable box sections and as secured in adjustable relation thereon by bolts 28 and 29, extending through slots 30, 31, in the slides 32, 33, carrying the rolls and adjustable in the vertical guideways 34, 35. These vertical positioning guide rolls are shown as journalled on the brackets or slides 32, 33, by screw studs 36, 37, enabling the ready removal and substitution of diiferent kinds of rolls or guides.

By the construction disclosed, the rolls may be made to open up as a pair of jaws, permitting the stock to be entered without dragging it or forcing it through the rolls. In this opening up operation, which is effected simply by loosening the hand screw 11, the upper edge guide roll 27 is carried away from over the lower edge guide 26, thus leaving the space between the straightener rolls clear to receive the stock. In this opened relation, the lower edge guide 26 forms a bottom support for the stock being placed and YES.

prevents the stock from dropping down below the straightener rolls.

While the structure disclosed constitutes a present preferred embodiment of the invention, it will be appreciated that changes may be made, all within the broad intent of the claims and it should be understood that the terms employed have been used in a descriptive rather than in a limiting sense, except possibly for limitations that may be imposed by the state of the prior art.

What is claimed is:

1. In a machine of the character disclosed, stock straightening means including opposed sets of straightening rolls and means for supporting one set of said rolls movable as a unit toward and away from the other set of rolls, and opposed guiding rolls, one shiftable with the movable set of rolls and the other associated with the companion set of rolls.

2. In a machine of the character disclosed, a strip. straightener comprising relatively movable boxes, slides set in side by side relation in said boxes, straightener rolls carried by said slides, individual adjusting means for said slides, readily releasable means for securing the boxes with the two sets of rolls in operative relation and opposed edge gaging rolls carried one by each of the relatively movable boxes.

3..In a machine of the character disclosed, a strip straightener comprising relatively movable boxes, slides set in side by side relation in said boxes, straightener rolls carried by said slides individual adjusting means for said slides, readily releasable means for securing the boxes with ,the two sets of rolls in operative relation, one

of said boxes being pivotally mounted for swinging movement toward and away from the other box, stop means for definitely positioning the boxes in respect to each other and a screw clamp 40 for releasably securing the boxes with the rolls in operative relation.

4. In a machine of the character disclosed, the

combination of roll supporting sections hingedly related on a substantially horizontal axis, straightener rolls mounted in said roll supporting sections, a lower edge guide carried by one of the roll supporting sections and located to support the stock when the roll supporting sections are separated for placing stock between the straightener rolls and an upper edge guide carried by the other roll supporting section to engage over the top of the stock positioned on the lower edge guide when the roll supporting sections are brought together.

5. In a machine of the character disclosed, the I combination of box sections relatively separable, straightener rollsvmounted in individually adjustable relation in said sections, means for individually securing said straightener rolls down in seated position in said box sections and means for individually adjusting the straightener rolls in said box sections.

. 6. In a-machine of the character disclosed, the combination'of a stationary support, a supporting member horizontally pivoted on said stationary support, straightener rolls mounted in adjustable cooperating relation on said stationary support and on said movable supporting member, stop means for positioning the pivoted member in definite hinged relation on the supporting member and screw means for securing the movable supporting member in such definite position on the stationary supporting member.

7; In a machine of the character disclosed, stock straightening means including opposed sets of strip straightening rolls, means for supporting one set of said rolls movable as a unit toward and away from the other setof rolls, opposed strip edge guides, one of said strip edge guides being shiftable with the movable set of rolls and the opposing strip edge guide being associated with the companion set of strip straightening rolls.
